Yura Sangyo Co., Ltd. offers "hex bolts" with a strength guarantee of 8.8. Most standard 8.8 hex bolts are made from boron steel or SWCH35K, but our product uses "SCM435" and is managed under appropriate heat treatment conditions, ensuring a strength of 8.8 even after being treated at high temperatures during hot-dip galvanization. Please feel free to contact us when placing an order. 【Hex Bolt Sizes】 - M10 x 20–75 - M12 x 30–75 - M16 x 35–100 - M20 x 40–100 - M22 x 55–120 - M24 x 60–120 - M27 x 70–150 - M30 x 70–150 *For more details, please download the PDF or feel free to contact us.

The "AZX912" is an ultra-lightweight cap screw that features hexagon socket bolts made from magnesium alloy, which has undergone anodizing treatment to enhance corrosion resistance. With a specific gravity of approximately 1.8, it is about two-thirds the weight of aluminum alloy (specific gravity 2.7) and about one-fourth that of steel, making it extremely lightweight. It utilizes magnesium alloy, which is an excellent material in terms of specific strength, specific rigidity, vibration absorption, and recyclability. The specific strength (strength per unit density) of the AZX912 bolts is more than three times that of soft steel. When guaranteeing equivalent strength with bolts, the size or number may increase, but the total weight can be kept to about one-third. 【Features】 ■ Addition of Ca (calcium) suppresses flammability ■ Tensile strength ranges from 250 to 320 MPa, with a 0.2% yield strength of 160 to 240 MPa ■ Strength comparable to A5056 ■ With the same tightening axial force, it experiences less axial force reduction and is less prone to loosening compared to steel bolts *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "Stainless Steel Low Head Cap Series." By reducing the height of the bolt head, it allows for tightening in confined spaces, enabling the miniaturization and weight reduction of assembly equipment. We offer a lineup of stainless steel low head caps, stainless steel low head caps, and stainless steel ultra-low head caps. The hexagonal bolt heads, equivalent to SUS304, are carefully machined and chamfered to keep the height low. 【Product Lineup】 ■ Stainless Steel Low Head Cap (Strength Classification: A2-70) ■ Stainless Steel Low Head Cap (Strength Classification: A2-70) ■ Stainless Steel Ultra-Low Head Cap (Strength Classification: A2-50) *For more details, please download the PDF or feel free to contact us.

"Tungsten disulfide (WS2)" is a product that excels in lubrication and demonstrates a low friction coefficient, solving issues of "seizing" and "galling" in vacuum environments. It alleviates troubles arising from machinery and equipment, reducing downtime. It addresses difficult friction, wear, sticking, galling, and erosion caused by various extreme environmental conditions, particularly ultra-high vacuum. 【What is WS2 Dry Film Coating?】 - Maintains dimensional accuracy with a coating thickness of less than 1μm and durability - Reduces the burden on personnel involved in maintenance work and lowers costs - Decreases the accumulation of deposits on sliding surfaces - Cleans the environment - Enhances safety *For more details, please download the PDF or feel free to contact us.

The 'DSA3015' developed by Daido Steel is a heat-resistant alloy of the precipitation-hardened austenitic type. With a unique design that limits nickel to about 30%, it achieves both high-temperature strength and oxidation resistance, while also excelling in cold workability, making it suitable for mass production of bolts and reducing costs. By adding aluminum and titanium, it exhibits high-temperature strength and stress relaxation characteristics due to the precipitation-strengthened phase. 【Features】 ■ High heat resistance ■ High strength ■ High corrosion resistance ■ Non-magnetic ■ Convenience *For more details, please download the PDF or feel free to contact us.
